Brief Summary:
Understanding the impact of dietary patterns, exercise, and behavior change in the prevention of disease is paramount to improving the health and well-being of future generations and economies. A gap in the research is the lack of data on factors that predict successful behavior change for sustained dietary practices chosen for health or other personal reasons. To date, no survey exists that was designed to target persons following a wide range of popular dietary patterns (e.g., Paleo, low-carb, vegetarian, vegan, Mediterranean, gluten-free, etc.). These dietary patterns, which offer great variation in macronutrient composition, are unique and unexplored in other similar surveys to date, making their examination innovative. Adhering to Dietary Approaches for Personal Taste (ADAPT) will be the first large cohort of its type that is focused on adherence to popular dietary patterns, providing the opportunity to better understand how individuals can be supported to successfully maintain a specific dietary practice, and, in the long-term, how these practices may influence parameters of healthy aging.

Primary Outcome Measures :
  1. Mean nutrient composition [ Time Frame: through study completion (data collection typically lasting 6-12 weeks per participant, but up to 1 year allowed) ]
    Compare actual intake calculated from participant-reported diet history questionnaires and/or diet recalls to targeted nutrient composition of the respective dietary pattern reported by the participant. Targeted nutrient composition will be calculated using 7-day meal plans from popular dietary patterns of interest. These 7-day meal plans will be generated from sources of nutrition information identified by participants in the ADAPT Feasibility Survey which was conducted in the summer of 2015 to demonstrate whether popular diet followers would be interested in participating in nutrition research.

  2. Dietary adherence [ Time Frame: through study completion (data collection typically lasting 6-12 weeks per participant, but up to 1 year allowed) ]
    The Mahalanobis distance equation will be used to measure the similarity between targeted and actual intake. Actual intake will be calculated from participant-reported diet history questionnaires and/or diet recalls. Targeted intake will be calculated using 7-day meal plans from the popular dietary patterns of interest. These 7-day meal plans will be generated from sources of nutrition information identified by participants in the ADAPT Feasibility Survey. Perfect adherence will be defined as 100% consistency with 0% deviation from targeted intakes.


Secondary Outcome Measures :
  1. Diet quality [ Time Frame: through study completion (data collection typically lasting 6-12 weeks per participant, but up to 1 year allowed ]
    Dietary intake data from diet history questionnaire and/or diet recalls will be used to create a Healthy Eating Index (HEI) score to measure diet quality

  2. Body weight [ Time Frame: through study completion (data collection typically lasting 6-12 weeks per participant, but up to 1 year allowed ]
    Body weight will be self-reported by participants

  3. Body mass index (BMI) [ Time Frame: through study completion (data collection typically lasting 6-12 weeks per participant, but up to 1 year allowed ]
    BMI will be calculated based on self-reported height and body weight using the following formula: BMI = (Weight in Pounds / (Height in inches x Height in inches)) x 703
